Use a fork to mix in butter. If it is too crumbly, mix it together with your hands. (The warmth of your hands will further soften the butter, creating a softer dough).
Refrigerate for 30 minutes to an hour, so that it is firm, but pliable.
Either roll the dough into a log and slice 1/2 inch discs, roll it into an 8 inch circle and cut it with a pizza cutter into 8 pieces, or roll the dough out until it is a 1/2 inch thick and use cookie cutters to cut the dough.
Leave space between each piece as they will spread some.
Bake at 325 for 25 – 30 minutes.
Notes
I like to add the grated peel from one orange and 1 1/2 teaspoons of orange extract to the batter.
